Malay children with DLD showed a clear asymmetry in comprehension of Wh-questions with a selective impairment for Which-NP questions compared to Who-questions. Age matched control performed at ceiling in all Wh-questions, while the language matched group reported a subject/object asymmetry selective for the Which-NP, as reported in other languages. In production both children with DLD and younger children had preference for the question with in-situ Wh elements, a structure allowed in colloquial Malay, but not produced by the age matched group. Several non-adult-like strategies were adopted by the children with DLD to avoid complex sentences, including substitution with Yes/No echo questions, production of the wrong Wh-question and use of a generic Wh element mana (Where). The study provides an insight on the development of Wh questions in both typical Malay children and children with DLD. Implications for the definition of a clinical marker for DLD in a free word language with Wh-in situ option will be discussed.
